TO ALL WHOM IT MAY CONCERN: i

Beit known that I, JOHN GRnNEn, of Warsaw, in the county of Kosciuslro, and State of Indiana, have invented an improved Heat-Radiator; andI do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings and letters of reference marked thereon, making a part of this description, in whieh- Figure 1 isa'central sectional elevation of my heat-radiator.

Figure 2, a horizontal section of the same, taken, through line X X, iig. 1.

Figure 3, a perspective representation ofthe elevating-cap, used toclose the draught of -radiator..

The nature of my invention consists in the .use of a doublefconical exterior or drum, havingv arranged internally a series of conical radiators conforming to the size and contour of said exterior, and are elevated or lowered, as the case may require, to control the heat, hy means of racks and a pinion, the latter having a shaftA extending through to the dutside of the radiator for the convenience of operating said inside cones. By this arrangement the escape of heat from a stove, furnace, or drum can he controlled to a much better advantage than when the cones are niade a permanent fixture to the inside of the radiator, and the heat can be shut oli' entirely, or allowed wholly to escape up the pipe, as required, by simply raising the elevating-cap so as to strike against a ilangc projecting inward from the `top of radiator.

Another advantage consists i-n the inner cones being readily raised and lowered with suoli rapidity as to loosen and shake oli' soot, cinders, ashes, and dirt, oro'ther extraneous matter which usually accumulates inside ofdrums, radiators, die.

In order to give a correct understanding of my invention, I have marked corresponding parts with similar letters, and willnow give a detailed description.

A A represents a double conical drum, made ofcommon sheet iron, or any kind ef suitable metallic plate, and terminating in a suitable pipe, J, for the convenience of attaching the stove pipe, anda pipe, K, for fitting on to o. stove, range, furnace, as the case may require. This part of the radiator is not considered new, but is used as a matter of convenience. A flange, n, iig. 1, is made to project inward from the upper part of the radiator A. A, for the purpose of forming a stop foren elevating-cap, M, te strike against when thedraught is to be shut off. This cap M is attached to eene F by means ef'uzetallic straps E, fig. 1, and has holes, through which a connecting-rod, D, is made to pass, und a rod, C, is tted and rigidly attached. The cones H and Gr are attached to red D, and made to move up and down when racks B B are operated by pinion P, Eg. 1. The

i upper conc F is made to slide en rod D, by which means all of the cones mentioned may be drawn to the centi-'e of radiator A, when it is desirable to open the draught to its utmost capacity, asseen by dotted lines Z Z Z, Btc. By this description it will be seen that conseil-l G'rV are made to run upward when cone F is made to run downward, and that, when the elevating-eap M is shut against the flange a, the cones' H will eecupyaposition near the lower part of AA, iig. 1. A:By means of this arrangement the lower cones HG and the upper cone F are opened or closed by the same movement of racks B B. These racks may be east solid to the rods C D, as most convenient, or may be attached'by screws, bolts, or rivets, the object being to place and arrange them so aste be conveniently operated by pinion P. I am not particular as to the number of cones H GF used in the radiator, only so that thegeneral features are retained, and the pinion P and racks B B are used as set forth. A curved strap, I, is rigidly attached to the lower part of outside A A, and has a hole through which the rod D is made to pass in its upward and downward motion, and is very important in guiding the lower end ofsaid rod, otherwise tho inner cones would have no support, resulting in their striking against plates A A, and preventing the racks from working ns well as would otherwise be the ease, as can be plainly seen. The shaft for operating pinion P is not shown in the drawings, it being a very simple arrnnrreinent passing through the part LL similar to n damperrod.

'F G H, substantially as und for the purpose set forth.

Operation.

The radiator can be adjusted for use hy means of the short pipes J K, arranged to connect with a stove and stove pipe in the usual manner. The draught can be controlled by turning pinion P, which will raise or lower cones F H G, giving a greater or less space between them and the outside A A, andavhen the draught is to be shut off the cup M can be drawn up against lange n, as seen at iig. l.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination of racks B B, pinion P, cap M, flange n, and rod D, arranged to operate the'dampercones JOHN GRABNER. Witnesses:
